The method for accessing the internet of things provided by the embodiment of the present invention is described below with reference to the internet of things system shown in fig. 1, the terminal 100 shown in fig. 2, and the network manager 200 shown in fig. 3.

The processing procedure of the gateway 200 is the same for each terminal 100 in fig. 1. The following describes an example of a process performed by the gateway 200 for one terminal 100.

As shown in fig. 4, a method for accessing an internet of things provided by the embodiment of the present invention includes:

s401, the terminal 100 sends a request message to the gateway 200.

Wherein, the request message is used for requesting to acquire the IP address.

Optionally, the request message conforms to a Dynamic Host Configuration Protocol (DHCP) protocol.

The request message includes an identification of the terminal 100.

Optionally, the identifier of the terminal 100 includes a product type of the terminal 100, a vendor name of the terminal 100, an operator of the terminal 100, and a version of the terminal 100.

Optionally, the request message further includes a preset key. The preset key is used for encrypting the request message, thereby increasing the security of the request message.

Illustratively, if the request message is a DHCP request (DHCP request), the DHCP request includes an identifier of the terminal 100 and a preset key. Table 1 shows the format of the identification of the terminal 100 and the preset key in the DHCP request. In table 1, PID represents a product type of the terminal 100, VID represents a vendor name of the terminal 100, SP represents an operator of the terminal 100, Version represents a Version of the terminal 100, and PWD represents a preset key. Of course, in practical applications, these information may also be represented by other symbols, which is not limited in the embodiments of the present invention.

TABLE 1

There may be a variety of values for the PID, VID, SP, Version, or PWD described above. The values are different, and the meanings expressed are different. For example: when the PID value is 0, the terminal is represented as a television; and when the PID value is 1, the terminal is represented as a refrigerator. The description of PID values herein is merely an example and is not a limitation on PID values.

Alternatively, the identifier and the preset key of the terminal 100 may be located in the option 60 (i.e., option 60) field in the DHCP request.

S402, the gateway 200 receives the request message sent by the terminal 100.

S403, the gateway 200 determines whether the terminal 100 is legitimate.

In the case where the request message includes the identity of the terminal 100, the gateway 200 determines whether the terminal 100 is legitimate according to the identity of the terminal 100.

In one implementation, if the identifier of the terminal 100 is in the preset identifier set, the gateway 200 determines that the terminal 100 is legal. Otherwise, the gateway 200 determines that the terminal 100 is illegal.

For example, if the preset identifier set is {1, …,10000 }; the values of PID, VID, SP, Version and PWD are all expressed by one bit.

If the PID value is 1 and the VID, SP, Version, and PWD values are all 0, the identifier of the terminal 100 is 10000. The identification "10000" is located in the set {1, …,10000}, the gateway 200 determines that the terminal 100 is legitimate.

If the values of PID and VID are both 1, and the values of SP, Version, and PWD are all 0, the identifier of the terminal 100 is 11000. The flag "11000" is not located in the set {1, …,10000}, the gateway 200 determines that the terminal 100 is illegal.

In a second implementation, the gateway 200 determines whether the terminal 100 is legal by determining whether the identifier of the terminal 100 satisfies a preset rule.

Besides the above manners, the gateway 200 may also determine whether the terminal 100 is legal by using other manners, which is not described in detail in the embodiments of the present invention.

In the case that the request message includes the identifier of the terminal 100 and the preset key, the gateway 200 determines whether the terminal 100 is legal or not according to the identifier of the terminal 100 and the preset key.

For example, after receiving the request message sent by the terminal 100, the gateway 200 first allocates a first IP address through a DHCP procedure, and then authenticates the extension information (the identifier of the terminal 100 and a preset key) of the terminal 100, sends the information of the eSIM card to the terminal 100 if the authentication is passed, and does not send the information of the eSIM card to the terminal 100 if the authentication is not passed, where the authentication is a terminal that determines whether the terminal 100 is customized by an operator.

If the gateway 200 determines that the terminal 100 is legitimate, the gateway 200 assigns an IP address (i.e., a first IP address described below) to the terminal 100 and transmits the eSIM card information to the terminal 100, i.e., proceeds to S404. If the gateway 200 determines that the terminal 100 is illegal, the gateway 200 allocates only an IP address (i.e., a first IP address described below) to the terminal 100. In the embodiment of the present invention, after the gateway 200 determines that the terminal 100 is illegal, the processing procedure of the gateway 200 may refer to the processing procedure of the gateway 200 in the prior art, which is not described in detail in the embodiment of the present invention.

S404, the gateway 200 assigns a first IP address to the terminal 100, and sends the first IP address and information of the pre-stored eSIM card to the terminal 100.

The information of the eSIM card includes a number corresponding to the eSIM card and a key corresponding to the eSIM card. After the gateway 200 transmits the information of the eSIM card to the terminal 100, the terminal 100 can complete network access according to the information of the eSIM card.

The gateway 200 may also transmit a network address of the eSIM card management platform (i.e., the internet of things server 300 in fig. 1) to the terminal 100, so that the terminal 100 determines an address of an internet of things to be connected.

Optionally, the gateway 200 may send the first IP address and the information of the pre-stored eSIM card to the terminal 200, and send the network address of the eSIM card management platform to the terminal 200; or may simultaneously send the network address of the eSIM card management platform (the internet of things server 300), the first IP address, and information of the pre-stored eSIM card to the terminal 200; the network address of the eSIM card management platform may also be sent to the terminal 200 first, and then the first IP address and the information of the pre-stored eSIM card may be sent to the terminal 200.

Optionally, the gateway 200 may further send a physical identifier of the gateway 200 to the terminal 100, so that the terminal 100 connects to the internet of things through the gateway 200 according to the physical address of the gateway 200.

For example, the information of the eSIM card may be information of the eSIM card for the home user, which is acquired by the gateway 200 through an over-the-air card writing process by using a network address of an eSIM card management platform (the internet of things server 300) preset in advance, or may be acquired by the gateway 200 through the communication interface 204 from a storage medium (for example, a usb disk, a mobile hard disk, a magnetic disk, or an optical disk, which is capable of storing information of the eSIM card).

The above eSIM card for the home subscriber means that all terminals 100 in the home can share one eSIM card to access the internet of things server 300.

For example, if the gateway 200 sends the eSIM authentication-related information to the terminal 100 through a DHCP message, the DHCP message includes information of an eSIM card (a number corresponding to the eSIM card and a key corresponding to the eSIM card), a network address of an eSIM card management platform (the internet of things server 300), a physical identifier of the gateway 200, an esimwd indicates the key corresponding to the eSIM card, an IMSI indicates the number corresponding to the eSIM card, a URL indicates the network address of the eSIM card management platform (the internet of things server 300), and an RGSN indicates the physical identifier of the gateway 200, which is also indicated by other letters, but the present invention is not limited thereto.

As shown in table 2, the eSIM authentication-related information includes: information of the eSIM card, a network address of the eSIM card management platform (the internet of things server 300), and a physical identification of the gateway 200, such as a media access control address (MAC)/Serial Number (SN). In table 2, IMSI is used to represent the information of the eSIM card obtained by the home gateway, esimwd is used to represent the key string corresponding to the eSIM card, URL (uniform resource locator) is used to represent the address of the eSIM card management platform, and RGSN is used to represent the physical identifier corresponding to the gateway 200.

TABLE 2

Alternatively, the eSIM authentication-related information described above may be located in an option 60 (i.e., option 60) field of the DHCP message.

S405, the terminal 100 receives the eSIM card information and the first IP address transmitted by the gateway 200.

In the case where the gateway 200 also transmits the network address of the eSIM card management platform (the internet of things server 300), the terminal 100 also receives the eSIM card management platform (the internet of things server 300) transmitted by the gateway 200.

In the case where the gateway 200 also transmits the physical identifier of the gateway 200, the terminal 100 also receives the physical identifier of the gateway 200 transmitted by the gateway 200.

S406, the terminal 100 sends a connection message to the gateway 200.

The connection message includes eSIM card information and a first IP address, and the connection message is used to request establishment of a connection between the first IP address and the internet of things, so that the terminal 100 can access the internet of things with the eSIM card information.

The connection message includes eSIM card information, a first IP address, and an identifier of the terminal.

Illustratively, after the terminal 100 obtains the sent eSIM card information and the first IP address returned by the gateway, the terminal 100 initiates an authentication message to the IP address corresponding to the URL of the eSIM card management platform, carrying the number of the eSIM card and the key corresponding to the eSIM card.

S407, the gateway 200 receives the connection message sent by the terminal 100.

S408, the gateway 200 sends a connection message to the core network equipment of the Internet of things.

Optionally, the gateway 200 further sends the physical identifier of the gateway 200 to the core network device of the internet of things. So that the internet of things server 300 uniformly manages all the terminals 100 connected to the gateway 200.

For example, the core network device of the internet of things may be a Broadband Remote Access Server (BRAS), or may be other core network devices, which is not limited in the present invention.

For example, after the gateway 200 obtains the connection message (authentication message) sent by the terminal 100, in order to ensure end-to-end security, the gateway 200 sends the connection message to the BRAS using the single encrypted VLAN channel, the BRAS forwards the connection message to the mobile core network, the mobile core network authenticates the connection message according to the data flow of the internet of things, and after the authentication is passed, the information of the terminal 100 is entered into the operator internet of things unified management platform (internet of things server 300) to perform corresponding management and charging.

As shown in fig. 5, the terminal 100 provided in the embodiment of the present invention is configured to execute the method for accessing to the internet of things, where the terminal 100 includes a first sending unit 501, a receiving unit 502, and a second sending unit 503.

Illustratively, as shown in fig. 2 and fig. 5, the first sending unit 501, the receiving unit 502, and the second sending unit 503 in fig. 5 communicate with other devices (e.g., the gateway 200) through the communication interface 104 in fig. 2. The first sending unit 501, the receiving unit 502, and the second sending unit 503 call the program in the memory 103 via the communication line 102 by the processor 101 in fig. 2 to execute the above method for accessing the internet of things.
